ok, so i have this dock connection in my car for ipods. i tried it with my iphone today, and it works fine, lets me browse through my songs from my radio, the apps sounds also come out of the cars speakers, but when i go to make a call, or receive a call, it goes through the phone only. is there an alternate phone app or something that would let me bypass that? because thats one thing i was really looking forward to, or some sort of tweak that would allow it?
